首先PhotoImage注意这里只支持gif格式的图片
|
1
|
photo = PhotoImage(file="D:/python/images/02.gif")
|
发现tkinter是只支持gif的格式，如果要加载png或者jpg的话就要使用PIL模块

from tkinter import *
from PIL import Image, ImageTk
root = Tk()
root.title('测试组python毕业题')
img = Image.open('ques.png') # 打开图片
photo = ImageTk.PhotoImage(img) # 用PIL模块的PhotoImage打开
imglabel = Label(root, image=photo)
imglabel.grid(row=0, column=0, columnspan=3)
Label(root, text="Answer:").grid(row=1, column=0, sticky=S + N)
answerEntry = Entry(root)
btn = Button(root, text="Submit", command='submit')
answerEntry.grid(row=1, column=1)
btn.grid(row=1, column=2)
mainloop()

但运行时会报
ModuleNotFoundError: No module named 'PIL'
运行命令:

pip install pillow

D:\Program Files\Python37>pip install pillow

如果运行该命令 显示
Requirement already satisfied: Pillow in c:\program files (x86)\python\lib\site-packages (3.4.2)
则表示已经安装过了
如果已安装则先卸载以获取最新的pillow
运行命令: pip uninstall pillow
然后运行:pip install pillow
就可以了
补充：解决python tkinter 展示jpg、png格式图片的问题
报错：

from tkinter import *
img = PhotoImage(file = r'D:\test\hero\暗黑元首\暗黑元首.jpg')
lable_show = Label(frame_show,imag = img)
|
解决：首先安装PIL库，使用pip命令
|
1
|
pip install pillow
|
然后使用PIL库获得ImageTk.PhotoImage对象代替tk.PhotoImage对象即可
